Excellent View of Low-Level Jet……..Few Showers/T’Storms……Stronger Winds Approaching (Will Improve Visibilities Greatly)

January 29th, 2013 at 12:25 am by under Chad's WLFI Weather Blog

Below is an excellent view of the strong low-level jet helping with forcing for storms in Illinois along & north of the warm front.  Notice the ripples with the drizzle/shower echoes in Illinois, clearly showing the wind-induced waves.

It is a ribbon of strong winds that becomes strongest at night that transport moist, unstable air & lift northward.  As Earth’s spins, the jet curves to the right (called Coriolis Effect).

A few passing showers & t’storms are possible tonight & tomorrow (30%………some of you will stay dry), but the bulk of it will be northwest & west of here.

Much stronger winds are approaching, which will increase visibilities greatly overnight-early Tuesday morning from 0-0.50 mile to 1-4 miles.

1-3″ still looks good for total rainfall with most of it falling Tuesday overnight.  1-2″ will largely fall, but there will be some isolated 2-3″ amounts, so kept it as 1-3″.  Sporadic damaging straight-line wind threat will exist overnight Tuesday & early, early Wednesday morning in our western half.  This forecast remains unchanged.

If higher dew points can move in, then isolated EF0-EF1 tornado threat will need to be introduced, but I am not ready to do that right now.

With the record warmth with highs of 61-66, winds may gust to 40 mph tomorrow & tomorrow night.
